HOT-AIR STOVE.

Specification of Letters Patent.

Patented July ill, 1916.

Application filed May 10, 1913. Serial No. 766,775.

To all whom it may concern:

Be it known that I, THOMAS WVARREN MIL- LER, a citizen of the UnitedStates, residing at VVaukon, in the county of Allamakee and State ofIowa, have invented certain new and useful Improvements in Hot-AirStoves; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to hot air stoves, and more particularly tostoves provided with a safety shield or screen.

One of the objects of the invention is the provision of a stove providedwith a safety shield adapted to be supported by the base of the stoveand to surround the body of the stove in spaced relation thereto.

Another object of the invention is the provision of a stove providedwith a safety shield formed of a section of wire screen having its edgesreinforced by a metallic frame provided with fastening devices forsecuring the shield upon the stove.

A further object of the invention is the provision of a stove providedwith a safety shield formed of a section of wire screen 1 having itsedges reinforced by a metallic frame, the screen and the frame beingprovided with recessed portions for surrounding the respective fueldoor, draft door, and stove pipe openings of the stove. And a furtherobject of the invention is the provision of a stove having a safetyshield so arranged thereon that the liability of injury to a person orto inflammable material coming in contact with the stove is obviated,while at the same time the proper radiation of the heat and thecirculation of air around and about the heated surface of the stove, isnot interfered with.

WVith these objects in view the invention consists of an improvedconstruction, arrangement and combination of parts of a safety shield orscreen and hot air stove, which will be hereinafter fully described andafterward specifically claimed.

In order that the construction and operation thereof may be readilycomprehended I have illustrated some approved embodiments of myinvention in the accompanying drawings, which I will now proceed tofully describe, and having reference to said drawings, in which 7 Figure1 represents, in front elevation, a stove provided with a safety shieldin accordance with my invention, Fig. 2 represents one form ofstiffening rim for my improved shield, Fig. 3 represents in elevationone-half of the shield which is constructed in accordance with amodification of my invcntion, Fig. a represents one of the strips used,said figure being a top plan view of the construction of strips shown inFig. 3, Fig. 5 represents a front view of a shield for application to astove having a coaldoor, Fig. 6 represents a rear view of a shieldapplicable to a stove having a stove pipe opening formed in the rearside thereof, and, Fig. 7 represents one means for securing the edges ofthe wire screening together.

Like reference characters, mark the same parts whenever they occur inone or more figures of the drawings.

Many persons, both children and adults, have been seriously burned byaccidentally pressing against stoves or other heat radiating bodies andmany confiagrations have occurred by the clothing of persons, or otherinflammable material, accidentally coming in contact with such bodies,and it has long been a desideratum to provide some means for theprevention of these catastrophes. After much experiment and extendedthought I have conceived and constructed what I consider to be a perfectpreventive for any such accidents and at the same time which will not inany wise interfere with the functions of the heat radiating devices.

Owing to divergence in the size, shapes and forms of such heat radiatingdevices, including stoves, I have found it necessary to modify theconstruction of my safety shield to suit the circumstances. Some stovesbeing of top feed design and cylindrical shape, require a cylindricalsafety appliance and may or may not require the provision for a door,such as an ash-door or a coal-feed door, and if a stove has a stove pipeprojecting from the side provision must be made to accommodate thisprojection also. With a view to meeting all these possibilities I haveconstructed the device illustrated in the drawings, in Fig. 1 of which 1frontof the stove. The top of the netting, in this instance, i'sprovided with a circu- V larly bent strip 16 to which the upper end ofthe wire of'the netting is secured. This be formed in an integral framestructure,"

if so desired. The shield is mounted to surround the stove at a suitabledistance there- L from and is supported on theb ase of the 15.

stoveby a circularly bent metal strip 15 secured'inan y suitable mannerto the bottom of the nettin'g, the reinforced side edges of the shieldoverlapping each other at the wire netting may consist of anyconventional 1 weavebut'is shown in the drawings as comprising,transversed strands 14? and longitudinal strands 14 The overlappingside edges of'the netting 14 are reinforced by metal strips, as ind':cated' at 17 ,"one of the strips, however, overlying the other, andbeing secured together by ,rivetsor bolts 18. These strips 17 extenddownwardly nearly to the ash-door where theyare secured to invertedL-shaped strips 19: which surround a cut-out portion of the netting andare secured to the bottom strip 15. i To provide for the coal-feed door,

a portion of the netting'will be cut away as T at 20, in Fig. 5, andsaid opening in the "netting will be edged or surrounded withthefsubstantially E-shaped metal strips 211 secured thereto by rivets22, bolts, or the like and in lieu of the strips 17, the outer of whichis shown in Fig. 1, central strips '23 and 24- being provided on themeeting edges of the netting 14:, superposed upon each other in a mannersimilar to the strips 17, and secured together by rivets 25 or the like,and also to the binding strips 21 of theo'p'ening 20, by means of rivets26 or like fasteners, the upper ends of strips 23 being secured to thetop strip 16, and the lower ends of the strips 2 1 being secured 'F'ig.1.

.20 is fastened to the edges of the wire "21 of the. opening,

The door 20 has the metallic frame 20 around the edgesthereof tocorrespond with the metallic strips 21 which border and reinforce saidopening. This metallic frame strands which compose the body of the doorthe same as does the screen, and hinges 20 i connect one side of themetallic frame 20 of the door with 'one of the metallic strips 4 andlikewise the latch 20 connects the other side of the frame 20 withtheopposite metallic strip 21. This arrangement provides a reinforced doorand door seating within the opening 20 and with the door lying flushwith the reinforcing strips 21 of the door opening 20.

lVhen it is desired to accommodate a stove pipe, the rear centralportion of the netting 14 is provided with strips 27 and 28, as in Fig.6, which are secured to the netting 1 1 by rivets 29 or other suitablesecuring means and at their inner ends are secured by rivets 30 to aring or circular strip of sheet metal 31 surrounding an opening32 formedin the netting through which the stove pipe may pass, the outer ends ofthe strips 27 and 28 being secured to the top strip 16 and the bottomstrip 15 respectively.

'The netting for an ordinary stove may be made in a single piece andjoined at its edges in the manner described in reference to theconstruction of Figs. 1, 5 and 6, or it may be desirable at times tomake the shield of separate and detachable semi-circular sections, asshown in Fig. 3. In this instance a strip 32 binds the top edge ofsufficient netting to extend half way around thestove to be shielded,while a front strip 33, and a rear strip 33, either integral with orsecured to the top strip 32, are secured in like manner to therespective side edges of the netting 34, said front strip beingcontinued in an inverted L-shaped angular form as at35 and 36 toaccommodate one-half of an ash-door and being further continued in theform of a bottom strip 37 to the rear strip 33. In making up thesesections the angular portion 35 and 36 and the binding strips 32, 33, 33and 37 may be made integral with the other strips or may be madeseparately therefrom, but I prefer, in this instance, to form the stripintegral. In any event all of the strips are properly secured to theedge of the netting and the strips 33 and 33 along the meeting edges ofthe netting are provided with holes 38 so that when two of thesesemicylindrical structures are brought together and their edgesoverlapped,suit able rivets orbolts maybe inserted through said holesand the sections thus secured together in cylindrical form, sub- 7stantially as shown in Fig. 1, the method to the. inverted L-shapedstrips 19 as in of securing being illustrated in. Fig. 2, securing boltsor rivets being designated 39 and the strip illustrated being twosections of top strip, as shown in Fig. 3, the strip illustrated in Fig.4 being the same but being shown detached.

While the sectional shield, above described and shown in part in Fig. 3,is formed 7 in sections of wire netting reinforced with an' integrallyformed frame structure, and is designed for a stove of the top feed typehaving a draft opening, the shield may be provided with a door and dooropening. This is accomplished by cutting away a portion of the screen 31 of each section, in a manner indicated at 20 in Fig. 5, reinforcingthe cut away portion of each section with a substantially lE-shapedreinforcing member, indicated at 21 in I i g. 5, which reinforcingmembers form an integral part of the overlapping strip mem bers 83 ofthe respective sections, and supplying the door opening thus formed witha door similar to the door 20 of Fig. 5. In addition to the dooropening, the sectional shield may also be provided with a stove pipeopening, similar to that indicated at 32 in Fig. 6, by formingsubstantially semicircular cut away portions in the rear continguousedges of the screen 34L of the sections, and reinforcing the cut awayportions at each side of the stove pipe opening thus formed withsubstantially semicircular reinforcing members which form an integralpart of each of the rear overlapping strip members 33 of the sections,each of the semicircular reinforcing members for the stove pipe openingbeing substantially equivalent to half of the ring member 31 shown inFig. 6.

While the constructions described cover the experiments which I havemade at this time, I desire it to be understood that the invention isnot to be confined to these forms, especially as variations may becomeadvisable or necessary in specific instances. The shields may be builtwith the stoves or they may be secured to stoves already built. When itis desired, in shipping separately from the stoves, it will be ofdecided advantage to so construct the shield as to permit it to beplaced in a flat crate or bundle. Hence I would vary the construction tomeet this requirement. Instead of fastening the two edges which meetperpendicularly in the manner described, the meeting edges could bebound on the edges with a metal strip, of lJ-shape or equivalent form incross section, and having afliXed to one edge of the strip suitableeyes, as at 40 in Fig. 7, which would be engaged in openings 41, throughwhich eyes a rod might be passed to secure the edges together, such'astening means being applicable to either two, three or four sectionshields, as might be desired.

Provision will be made in my shields to accommodate any projections oropening of a stove not hereinbefo-re mentioned, such for instance asdraft dampers, sliding doors or the like, within the scope of theinvention, which is intended to be applied to any and all various formsof stoves and heating devices now in use or which may hereafter comeinto use.

Ordinarily the shield would probably be placed about two inches from theheat radiating body, but experiment has determined that it is possibleto place it within an inch of the surface of the heating body, withoutinjuring clothing, inflammable material or the person, on account of thenonheat absorbing qualities of the wire shield itself, and thecirculation of air between the wire and the heating body.

Among the many advantages which I claimfor my construction may be namedthe following: It occupies no floor space save that required by thestove. It offers no hindrance when giving the stove attention in the wayof charging with fuel or removing ashes. Being attached to the stove orresting on the stove base or foot rests, the use of posts or standardsand the consequent fastening to the floor is obviated which fasteningwith screws on an uncarpeted floor would render same unsightly orwhenever it became necessary to make such fastening through a rug orcarpet, injury would result. It offers no hindrance when changingposition of stove, removing, setting up or taking down. Permits onedesiring warmth to take a position equally close to a stove so fitted aswould be the case with a stove not fitted with the appliance. It offersnov hindrance whatsoever when sweeping, cleaning, or dusting about thestove. Enhances the appearance of the stove. Being in effect a part ofthe stove or an appliance therefor, liability of lack of adjustment isovercome as might be the case were posts or standards employed. Owing tonon heat absorbing qualities of the woven wire there is obviously noradiation therefrom, which permits the appliance to be placed very nearthe stove body and still affords protection to the person or clothing.The form or shape of the appliance may be made to conform to the form orshape of the stove or ornaments thereon without rendering the applianceless ethcient.

My device envelops the entire stove body, that is from bottom of firepotto top rim, and therefore, it follows that no injury to a child, invalidor aged person could result from falling against or over the applianceas might be were protection afforded by a contrivance not so constructedor designed.

, Having thus fully described my invention, what I claim as new anddesire to secure by Letters Patent of the United States is:
